Answer 2

(3k+4l)(3k+4l)

Identity to use: (a+b)(a+b) = (a+b)²

(a+b)² = a² + 2ab + b²

a = 3k

b = 4l

(3k)² + 2(3k)(4l) + (4l)²

9k² + 24kl + 16l²

(ax² + by²)(ax² + by²)

Identity to use: (a+b)(a+b) = (a+b)²

(a+b)² = a² + 2ab + b²

a = ax²

b = by²

(ax²)² + 2(ax²)(by²) + (by²)²

a²x⁴ + 2ax²by² + b²y⁴

(7d - 9e)(7d - 9e)

Identity to use : (a-b)(a-b) = (a-b)²

(a-b)² = a² - 2ab + b²

a = 7d

b = 9e

(7d)² - 2(7d)(9e) + (9e)²

49d² - 126de + 81e²

(m² - n²)(m² + n²)

Identity to use: (a-b)(a+b) = a² - b²

a = m²

b = n²

(m²)² - (n²)²

m⁴ - n⁴

Hope it helps

have a great day
